To all whom it may concern: g

Be it known that we, URIAH H; GOBLE and ALEXANDER STUART, of Urhana, inthe con 11 ty inciple that distinguishes the samefromall ulllel'machines before known, reference" being hat to the accompanyingdrawings, making apart of this specificatiomin which--- Figure l is aperspective view of our harvesting-machine; Fig. 2, a side elevationFig. 3, a vertical section in the liner :0 of Fig. 2, and Fig. 4 aperspective view of a portion of the machine detached.

Similar letters indicate like parts in all the figures. V

In our improved harvesting machine we make use of the reciprocatingsaw-teeth cutting apparatus, the movements connected with which, as wellas the general features of the frame-work of the machine, are arrangedand constructed as represented in the drawings, or in any well-known orusual manner.

The nature of our invention consists in the combination of an improvedself-acting rake,

H, with the platform Q,'in the rear of the cut-- ting apparatus, andwith't-hegearing of the machine, inthe particular manner hereinafter setforth, for the purpose of removing the straw and grain from the platformand depositing the same in smooth and even layers upon the ground forbinding. Our improved harvesting-ma chinerests upon the maindriving-wheel A on the shaftt'and the auxiliary supportingwheels P andZ.

a is a vertical crankshaft, which communi-i cates motion to the cuttersthrough the medium of the pitman (1. Motion is transmitted to thecrank-shaft'a, from .the main shaft t, through the medium of the beveledtoothed wheel U, (on the shaft 6,) matching into the bevel-pinion V onthe shaft 0, thetoothed whee-l W on the shaft 0 matching into the pinionX on the intermediate shaft, b, which pinion X matches into the-pinionyou the crank-shaft a.

T T are standards rising from the body of the machine, supportingbetween them the two shafts F K, a

S S- are inclined braces rising from the corners of the outer extremityof the apron Q, and joined together at their upper ends, forming thesupporting-bearing of theeuter-end of the rotating rake-shaft G. Theinnerend of the rake-shaft is jointed to and supported-by the end oftheshai't F, as shown in Fig.1. The rake H is connectedto thearms L-L,

projecting from the shaft G, in such a manner that it has aslidingradial motion-"upon the arms as the shaft'is revolved. The rakeiscomposed of the head q,let into and'fsecured in the extremities ofthearms'J J; and the-bar a, se-

cured-to'thearm'sJ J,.-a short distance from and parallel with therake-head, with a-cover-- 'ing of canvas o'r other suitable materialsecured to and extending from the bar r to the rake-head: The rake isconnected to theshaft G in the manner represented in'Fig, 1,10. wit:

The bands not are secured to the outer ends of thearms L L, and looselyembrace the rakearms J J. The metallic rods pp, secured'to andprojecting from the inner ends of the-rakearins 'J J, pass through themetallic eyesz z,

the shanks of which are driven into the shaft 1 Gr, which mode' ofconnection allows the :rake to'slidefreely out and inupon thearms .L' Las the shaftrevolves." W hen the rake descends below a horizontalposition as. theshaft revolves its weight causes it toslide. outwarduntil it is arrested bythe heads at the extremities of the-rods p pstriking against the e-yes z 2. When their-take, as it is carried upwardby the revolutions of the shaft, rises above a horizontal position itsweight causes it to slide inward upon the arms L L, into the position"represented in Fig. 1. Baketeeth k k, of suitable. length and therequisitedistancc from each other, are let into and project from therake-head q. Asthe rake revolves, as above set forth, and slides forwardon the arms L L, the points of the teeth puss within a very shortdistance of the front edge of. the platform Q, just in the rear of thecutters, where theyenter the straw of the grain and conduct the same tothe rear. As the rakemoves toward the rear the rollers M M on theproiecting ends of the bar 1* pass onto the horizontal ways N, securedto the inner sides of the vertical ends 0 O of. the platform, which waysand rollers, with the manner of attaching the rake to the arms of theshaft, cause the rake to move across the platform in a line parallelthereto,.until the points of the rake-teeth reach the adjustable wing R,at the rear edge of the platform, when the rake commences to rise,

' slow to a comparatively rapid movement.

the teeth passing nearly in contact with'the elevated wing R, and asthey pass above and to the rear of the wing R the straw of the graindrops vertically fro'mtherake-teeth upon.

the ground in a smooth and-'even layer-for con- Veniently gathering upand binding.

. Motion is imparted .to the rake-shaft G through the mediumofa band orchain passing from the pulley B on the main' shaft 11 to and around thepulley C on the-shaft K, and

the pinion -D, placed .eccentrically. upon the shaft K; matchingtintothe elliptical toothed wheel E on the shaft F, to which the shaft G isjointed. This manner of driving theshaft G-gives t it'an unQquaI motionin different portions of its revolution, varying from avery At the timethat the teeth of the pinion D nearest to its shaft are matching int-othe teeth of the toothed elliptical-wheel E most distant from the shaftF the shaft G will have imparted to it a very slow motion, whichmovement will gradually increase in speed until the teeth of the pinionD most distant from its shaft matches into the teeth in E nearest to theshaft F, and vice versa. The object of this unequal motion of therake-shaft'G-is .to give agraduallyxliminishing movement to the rake as.it

passes across the platfornf, and a very slow motion at the momentthat-the grain fallsfrom the'teeth,for the purpose of allowing the strawto drop evenly from the teeth upon the ground instead of being thrownsuddenly rearward therefrom into a tangled heap, which would take placeif the rake had a rapidmovement at the moment that the straw'wasdischarged therefrom.

1n going from placeto place with our improved harvesting-machine, thepulley B is allowed to play loosely upon the main. shaftt by'detnchingtherefrom the gland hyliig. 3,.

by neans of the l'ever'l, Fig. 1, and thereby causingthe rake to remainstationary when not required for use.

The'cutting apparatus is detached from-the I driving-shaft i, whennotrequired for use, by

elevating the shaft 1) in its bearings by means of the lever m, as shownin Figs. 1 and 2, and throwing the pinion X out of gear with. thetoothed wheel W on the shaft 0.

What we claim as our invention, and desire tosecure by Letters Patent.isg 1. The combination and arrangement by which we cause the rotatingmkeH to pass horizontally across the platform,Q-'-'to wit,

securing the .rake-to the shaft (1; .in such a manner that it canslidefreely to and from the same, placing rollers M M up'onthe*pr'ojecting ends of the bar r, parallelwith the rakehead,'ope'rating with the horizontalways N, secured to the inner sides of the verticalends 0 Q ofthe platform Q, substantially as here. in set forth.

. 2. The imparting an'uneqnal motion to the rake as it revolves, 'forthe purpose herein set forth, by means of the eccentric pinion D,

"matching with the elliptical toothed wheelE, substantiall v as hereinset forth. 4
